MATHEW F. IBIERSDORF, OF LOS ANGELES, CALIFORNIA.

COMBINED LooK AND BUTT GAGE.

To all whom it-mag concern Be it known that I, MATHEW F. BIERS- Donr, a citizen of the United States, and a resident of Los Angeles, in the. county of Los Angeles and State of California, have invented a new and useful Combined Lock and Butt Gage, of which the following is'a specification.

This invention relates to a gage for use in the fitting and hanging of doors and sash and the placing of the hinges and locks on same. 5

The object of this invention is to provide a gage that will accurately mark the door for both sides of the lock with one stroke, and likewise mark the j amb for both sides of the strike plate, and so adjusted as to leave the necessary clearance between the door and rabbet, combined with this-gage and independent of the lock gage is a butt-gage, and also a scribing bar that'can be used as an ordinary gage. r

In the accompanying drawings forming part of this specification, Figure 1, is a perspective view of the gage, Fig. 2 is an elevation. Fig. 3 is a perspective view of the casing or frame cut from a rectangular tube.

Fig. 4 shows the face plate. Fig. 5 is a transverse section through the gage on line tt, Fig. 2. Fig. 6 is a detail of the clamp and mechanism used to clamp together the two bars of the lock gage. Fig. 7 is a longitudinal section through the gage on line 1 -43 Fig. 1; Fig. 8 is a longitudinal section through the gage on line ss, Fig. 2. Fig. 9 shows the scribing bar of the butt gage.

Fig. 11 shows the scribing bar of the ordinary gage. Figs. 10 and 12 show the two scribing bars of the lock gage separately. Fig. 13 shows the same two bars placed together in their working position. Fig. 14; is a longitudinal section through the end of a scribingbar on line M, Fig. 7. Fig. 15.

is a transverse section through the end of a scribing bar on line wm, Fig. 9. And Fig. 16 is a detail of the reversible and adjustable point used in connection with the scribing bars.

Similar numerals refer to similar parts throughout the different views.

The improved gage here shown and described, is primarily adapted for use in connection with. the fitting of butts and locks, to doors, sash, jambs, and the like, and comprises a casing or frame, with several scrib- Specification of Iletters Patent. Y

ing bars slidably arranged longitudinally therein. The frameA, is formed from a' rectangular tube of the shape shown in Fig. 3, the wings 1 being turned downwardly and inwardly, closing the end as shown in Figs. 1 and 7, and secured in place by staples-2, the wings 3 on the opposite end of the frame being turned outward and upward, and against the back of the face plate E, and secured to same by the rivets 4, as shown in Fig. 7. In the face plate B shown in Fig. 4, is provided a plurality of openings, through which operate the several scribing bars slidably arranged longitudinally in the frame. The scribing bars of the lock gage C and D are shown in Figs. 10 and 12, said bars being tongued and grooved, bar C being provided witha groove 5, and barD with a tongue 6, the two bars made to slide longitudinally and against each other. One end of eachbar operates through opening 7 in the face plate B, the two bars being guided by the thumb-screw 8, through the longitudi- Said bars are adj ust able longitudinally, and when thus adjusted secured in place by the clamp 10, which encircles both bars and engages recess 14:, provided near the inner end of bar 0, the thumb screw 8 passing through said clamp and being threaded into the opposite side, the shoulder 11 acting against the washer 12, thus clamping the two bars together at any desired adjustment. The locking nut 13 acting against the outer side of the frame, permits the bars after they have been adjusted and locked together, to be moved longitudinally and locked at any desired point. To each end of each bar is secured a scribing point 15, shown in Fig. 16, hereinafter described, the points on the inner ends of said bars, operating through the longitudinal slot 16 in the frame.

E represents the scribing bar of the butt gage, as shown in Fig. 9, and is slidably fitted longitudinally'into the frame, and so arranged as not to conflict with the operation of .the other scribing bars, as shown in Figs. 1, 2, and 7, one end of the bar projecting through the opening 17, in the face plate B, the bar being guided by the thumb-screw 18, which engages the longitudinal slot 19 in the frame, the thumb-screw being threaded into the bar, with the washer 21 between the bar and the inner side of the frame. To each end of said bar is secured a scribing point 15, the inner point operating through the longitudinal slot 20 in the frame.

The scribing bar F of the ordinary gage, shown in Fig. 11, operates longitudinally through opening 22, in face plate B, being" guided by the thumb-screw 23, which engages the longitudinal slot 24: in the frame, the thumb-screw being threaded into said bar, with the washer 25, between the bar and the inner side of the frame. To the outer end of the bar is secured the scribing point 15.

The scribing points 15' shown in detail in Fig. 16, are adapted to fit snugly into the slots provided in the ends of the several scribing bars, and are adjustable longitudinally in said slots, and secured in place by the set-screw 26, these points being reversible, presenting a straight or perpendicular cutting edge on one side, and by reversing the point it transfers this straight cutting edge to the opposite side. Withthe points thus set and properly adjusted,..and using the face plate of the gage, as a guide along the side of the door or sash, and the opposite end of the gage, as a guide in :the rabbet of the jamb, the accurate markings for the relative position of both locks and butts, on both door and jam'b may be had.

What I claim as my invention, ist

The combination in a lock and butt gage, of a frame formed of one piece of thin metal, .a face plate aflixed to one end of said frame said face plate having openings therein, a plurality of scribing bars slidably fitted through said openings into said frame, one bar provided with scribing points at each end, a scribing point on the outer end of one bar, apair of bars tongued and grooved and made to move longitudinally against each other, a clamp within said frame engaging said bars said frame having .a slot therein a thumb-screw through said slot and screwed into the opposite side ofsaid clamp, a lock nut on the thumb-screw on the outer side of the frame, a shoulder on :said thumb screw, :a washer co-acting with said shoulder and against :the side of said clamp scribing points on each end of said bars, said frame having openings through which the scribing points on :the inner ends of said bars operate.

In testimony whereof I aflix mysignature in the presence of two witnesses.
